ICSE − Q & A

Guys... Now that physics is over, let's talk math. I'm kinda proud of my mathematical capability, egotistic even. So, get me some good by papers- and by good I mean GOOD- God like super tough papers. So, just gimme some links
Thanks.

Fully textbook based non application paper

An engine can pump 30000 litres of water to a vertical height of 45m in 10 minutes. Calculate the power of the machine if it's efficiency is 80%.[g=10m/s2 , density of water=1000kg/m3]
What answer doyou get?
